In a mixing bowl, combine ½ cup of curd and 2 tbsp of oil. Mix well and whisk the mixture for 2 minutes.
Now add ½ tsp of turmeric powder, salt to taste, 1 tsp of red chili powder, a pinch of hing, ½ tsp of ajwain, 1 tsp of fennel seeds, 2 tbsp of white sesame seeds, 3 tbsp of jaggery, ½ tsp of baking soda, and 1 tsp of lemon juice. Mix well until the masala combines and the mixture becomes slightly frothy.
Next, add 2 cups of chopped methi leaves, 1 tbsp of green chili paste, 1 tbsp of ginger-garlic paste, ½ cup of coriander leaves, 1.5 cups of bajri flour, ¼ cup of wheat flour, and ¼ cup of rava. Mix well.
Gradually add water and knead into a soft dough for the vada.
Take a cotton cloth and slightly wet it. Place small, ball-sized portions of the dough on it. Flatten them using a bowl or cup, apply some water and sesame seeds on them, and shape all the vada in the same way.
Heat oil and add the vada to it. Sprinkle some hot oil on the vada so they become fluffy and fry them on a medium flame until they become crispy on both sides.
Remove the fried vada and place them on a wire rack to allow excess oil to drain off.
Serve the bajri methi vada with chutney and fried chilies.
